For the following process
`H _(2)O (l) (1` bar `373.15K) hArr H_(2)O (g)`
(1 bar, 373.15 K ) identify the correct set of thermodynamic parameters.

Options

A. `Delta G=0, Delta S = + ve`
B. `Delta G =0, Delta S =- v e`
C. `Delta G = + ve, Delta S =0`
D. `Delta G=- ve, Delta S = + ve`

Answer

A

Explanation

State changes from liquid to gaseous thus movement of particles increases and hence, entropy change is positive. There is no change in pressure and temperature so change in G is zero.
